DRAIN PIPE FOR BRIDGE FLOOR SLAB
To provide a drain pipe for bridge floor slab which makes it possible to achieve good drainage even if a water-resistant layer is degraded.SOLUTION: A drain pipe is provided, comprising a main body pipe having an opened upper end and whose lower end is connected with a discharge pipe, an upper structure body arranged on the upper part of the main body pipe, and a water permeable filter arranged around the upper part of the main body pipe and formed of a material having both the permeability and heat resistance. A plurality of slits is provided at a fixed interval on the circumference of the upper edge of the main body pipe. The upper structure body has a cylindrical cap pipe having an outer diameter slightly smaller than the inner diameter of the main body pipe, and a grating arranged on the lower end of the cap pipe; it is configured so that water built up between the bridge floor slab and the water-resistant layer passes through a slit via a water filter, and then flows down into the main body pipe from the clearance between the main body pipe and the cap pipe.SELECTED DRAWING: Figure 1
【課題】防水層が劣化した場合であって良好な排水を可能にする橋梁床版用排水パイプを提供する。【解決手段】上端が開放し、下端に排出管が接続された本体管と、本体管の上部に配置された上部構造体と、本体管の上部の周囲に配置され、透水性と耐熱性を兼備した材料で形成された透水フィルタとを備え、本体管の上端の周縁部に、所定間隔隔てた複数個のスリットが設けられており、上部構造体が、本体管の内径よりも僅かに小径の外径をもつ円筒形のキャップ管と、キャップ管の下端に配置された目皿とを有しており、橋梁床版と防水層との間に滞留した水が、透水フィルタを介してスリットを通り、本体管とキャップ管との間の隙間から本体管内に流下するように構成されていることを特徴とする排水パイプが提供される。【選択図】 図１
